PERCOLATOR.

Liltlltlll Application filed December 2, 1914.

To all whom 'it may cof/cern Be it known. that I, BURTON H. COOK, a citizen of the United States, and resident of Brooklyn, in the county of Kings and State el New York, have invented certain new and useful Improvements in Percolators, of which the following is a specification.

)ly invention relates to percolators.

lt. relates particularly to a new and improved percolator, in which, among other novel and useful features, I employ a wateracket inclosing the percolated liquid, and I make the percolating operation automatic.

'lhe object of my invention is to provide a simple, cheaply constructed automatically operating and easily dcmounted percolator lor family and public uses.

To carry out my invention, I construct the outer receptacle containing the percolati'ng liquid as a water-jacket for the percolated liquid, and l provide means for automatically delivering the percolating liquid to the material that is under treatment.

ln the drawings attached to and forming a part ot' this specification: Figure l shows a vertical section through the essential parts of the invention; Fig. 2, a similar section, showing also a modified form of the distribliter; Fig. 3 is a section on the line A-A of Fig. l; Fig. vl, a section on the line B-B, of Fig. l.

Referring to the drawings,iin which similar reference characters designate similar partsz-l is the outside vessel having the usual cover 2, lilling pipe 3 and outlet spout 4; 5 is the receptacle for holding the percolatcd liquid; (i. the cotlee or other material being treated. the receptacle being provided with the usual sieve bottom 7; 8 is the liquid that has percolatcd through the sieve; 9 the unter-jacket surrounding the receptacle 5 holding the percolated liquid; 10 is a tube for supplying the percolating liquid located within the. water-jacket 9 'and extending nearly to the bottom thereof; 1l is a plug adapted to furnish a divided stream to the distributer l2, whieh is detachably held by the bayonet joint 13 to the cover 2 (Fig. l) l-l is a. modified form of the distributor detachably connected to the supply tube l() by slipping its bent end l5 over the end of the siphon, and 1G is a valve for controlling the flow from the siphon to the distributor.

The operation of the device is easily understood from the drawings: The parts being set up as shown, the water is introduced Specification of Letters Patent.

Serial No. 875,057.

through the filling pipe 3 into the water- ]acket 9. When the percolator is subjected to h eat the water in the watenjacket, beeomlnghot, rises through the supply' tube 10, passing through the divided openings ll into the coffee containing strainer G and collects in the bottom, as shown at 8. in order to control the supply of water, so as to keep the percolated liquid at the proper strength, there inserted in the supply tube lOlthe valve lll (Figs. l and Q).

There are manifold advantages in my pcrcolator over those known to me, among which may be mentioned the following: First. the water contained in the water jacket is in direct Contact with the source of heat, and the fact that it is a Water-jacket assures the easy communication ot' its heat to the percolated liquid, and hinders to a very great extent the dissipation of heat from the same. Second, the ailtomatic suppl v tube renders the device constant and certain in its action, and its being located inside Ot' the water-jacket obviates the having a pipe in the middle of the percolator, which might be easily misplaced or lost. Third, the easy removal of the parts under action makes my device simple and sanitary. ()ther advantages are obvious from the drawings.

Having thus fully described and illustrated my invention, what I claim, is:

l. A percolator having an outer casing and an inner chamber, the outer casing constituting a'water compartment and the inner compartmentl constituting a liquid coi"- fee receptacle, a tube leading from near the bottom of the water compartment to a point above the top of the coffee receptacle, said tube being located'in the water compartment, a container for the ground cotfee at the top ot' the coffee compartment, said container being open on its top side, av distributer receiving the water from said tube and located above the collec container, said distributer having a number 'ot' holes for distributing the boiling water and a single cover closing the top of the percolator whereby when the cover is removed the coffee container is rendered accessible without the removal oi' additional parts.

Q. A percolator having an outer casing and an inner chamber, the outer casing constituting a water conipartment and the inner compartment constituting a liquid colifee receptacle, a tube leading from near the Patented July lll, l 916.

bottom of the water compartment to a point above the top of the coffee receptacle, said tube being located in the water compartment, a container for the ground coffee at the top of the coffee compartment, said container being open at its top side, a hollow distributer having a detachable connection with the top of said tube, said distributor extending over the open side of the coffee vtube being located in the water compartment, a container for the ground coffee at the top of the coffee compartment, said container being open at its top side, a hollow distributer having a pipe arranged centrally at its top and curved downwardly to detachably Aengage the top of said tube, said distributer extending over the open top of the coffee container.

4. A percolator having an outer casing and an inner chamber, the outer casing constituting a water compartment and the inner compartment constituting a liquid coffee receptacle, a tube leading from near the bottom ofthe water compartment to a point above the top of the coffee receptacle, said container being open at its top side, a hollow distributer having a pipe arranged centrally at its top and curved downwardly todetachably engage the top of' said tube, said distributer extending over the'open top of the I said distributer.

5. A percolator having an outer casing and an inner chamber, the outer casing constituting a water compartment and having a cover at its top, the inner chamber being located below said cover, a ground coffee container at the top of' said inner chamber, a tube in the water compartment leading to the top of the inner chamber, a substantially circular distributer, a tube leading centrally from the top of said distributer and thence downwardly, and detachably connected to the water tube, said tube being partially housed in said cover, and said distributer being located directly above the ground coffee container, a valve located above said tube for graduating the amount of' boiling water fed to said dist-ributer, whereby upon opening said cover the distributer valve and coffee container are rendered accessible.

G. A percolator comprising an outer water casing, an inner liquid coffee compartment, a coffee container atthe top of said coffee compartment, a tube leading from said water container'to a point above the coffee, a distribute-.r above the coffee retainer and a valve for said distributer, said valve being located above the coffee container.
